BV421 Rat Anti-Mouse Vα2 TCR
BV421 Rat Anti-Mouse Vα2 TCR
Flow cytometric analysis of Vα2 TCR expression on mouse lymph node cells.  Lymph node cells from a BALB/c mouse were stained with FITC Rat anti-Mouse CD4 (Cat. No. 553729/557307/561828) and FITC Rat anti-Mouse CD8b (Cat. No. 553040/561968) in addition to either a BD Horizon™ BV421 Rat IgG2a, λ isotype control (Cat. No. 562965, Left Panel) or with the BD Horizon™ BV421 Rat anti-Mouse Vα2 TCR antibody (Cat. No. 562944, Right Panel).  Two-color flow cytometric dot plots show the correlated expression of Vα2 TCR (or Ig Isotype control staining) versus CD4 and CD8b were derived from gated events with the forward and side light-scattering characteristics of viable lymph node cells.  Flow cytometry was performed using a BD™ LSR II Flow Cytometry System.

Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with BD Horizon BV421 under optimum conditions, and unconjugated antibody and free BD Horizon BV421 were removed.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  3. An isotype control should be used at the same concentration as the antibody of interest.
  4. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  5. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

B20.1

The B20.1 monoclonal antibody specifically binds to most members of the Vα2 T-cell Receptor (TCR) subfamily in mice having the a, b, and c haplotypes of the Tcrb gene complex. B20.1 antibody may crossreact with Vδ8 TCR, which shares >90% sequence homology with Vα2 TCR. Levels of B20.1+ T cells appear to be influenced by Vα haplotypes. Moreover, the frequencies of Vα2+ CD8+ and CD4+ T cells are influenced by H-2 haplotypes.

The antibody was conjugated to BD Horizon™ BV421 which is part of the BD Horizon™ Brilliant Violet™ family of dyes.  With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon™ BV421  can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon™ BV421  conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue™ conjugates.

BV421
The BD Horizon Brilliant Violet™ 421 (BV421) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye has an excitation maximum (Ex Max) of 407-nm and an emission maximum (Em Max) at 423-nm. Driven by BD innovation, BV421 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 420-nm (e.g., a 431/28-nm or 450/50-nm bandpass filter). BV421 is an ideal alternative for V450 as it is approximately ten times brighter with less spillover into the BV510/V500 detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
